Installing 0.9

Information on installing builds from the 0.9 (July 2009) release.

As of 0.9 M4, e4 provides an "all in one" download. This is a product that contains everything you would ever need to develop e4: the latest Eclipse SDK, EMF SDK, and all of the e4 bundles and source code. Simply download the zip, unzip it, and run the eclipse.exe as you would for the basic Eclipse platform. The 0.9 release build is available here.

[1] Note that the Eclipse e4 UI work also requires the EMF runtime. This will be brought in automatically. However, if you wish to view or edit the UI model and you're not a fan of XML source editing, you will want to install the EMF SDK which provides the EMF .xmi editor. Follow "Help" -> "Install New Software..." -> "Models and Model Development" -> "EMF SDK - Eclipse Modeling Framework SDK 2.4.1 or 2.5.0", then restart Eclipse.
